SYRINGE.

SPECIFICATION forming part of Letters Patent No. 264,904, dated September 26, 1882.

Application filed May 18, 1882. (No model.)

10 all whom it may concern:

Be it known that I, STEPHEN G. SMITH, of Hannibal, Missouri, have made a new and useful I mprovementin Urethral Syringes, of which the followingis a full, clear, and exact description, reference being bad to the annexed drawings, making part of this specification, in whicht Figure 1 is a side elevation; and Fig. 2, a 10. sectional view upon an enlarged scale, showing the parts immediately connected with the nozzle.

The same letters denote the same parts. The present invention is an improvement in 1 5 urethral syringes, having a flange surrounding a the syringe-nozzle. p A represents the improved syringe. It is preferably of the ball form shown.

B represents the chamber of the syringe. 0 represents the nozzle. It is a flexible one. D represents a conoidal flange surrounding the nozzle. Itisproperly arranged and formed to compress the penis around the nozzle when.

the syringe is being used, the operation being 2 5 as follows: The nozzle 0 is introduced into the urethra until the flangeD encounters the penis. Then by inserting the nozzle a short distance farther the flange D is caused to bear upon the exterior'of the penis, and to compress the penis in the vicinity of the nozzle. The effect is to close the urethra around the nozzle and prevent the escape of the fluid being introduced by the syringe; and by being thus able to confine the'fluid within the urethra the fluid'can 3 5 be introduced much more effectually into the inner part of the urethra. The flange D is especially valuable in connection with a flexible nozzle such as is used in the present connection. 7 The liability of injuring or paining the patient is also much lessened in using a flexible nozzle, as, in such case, all that portion of the syringe that is outside the penis can be moved without producing a strain upon the urethra.

The flange D in practice ispret'erably at tached to the syringe, as shown in Fig. 2- that is, to a neck, D-being made preferably of hard rubber or other rigid material, and in one piece with the neck. The neck in turn is attached to the ball B" by means of the hollow screw E.

The nozzle 0 is attached to the neck D preferably as follows: The longitudinal perforation at in the neck is narrowed at the .upper end, 01. A perforated plug, F, is then screwed upward into. the perforation d, and so as to confine the lower end of the nozzle between the plug and the narrowed part of the perforation.

In this way of attaching the nozzle thereis less liability of itsbecoming accidentally detached from the body of the syringe.

I claim- 1. Ina syringe, the perforated and tapered O. D. MOODY, CHARLES PIGKLES.
